Butcher’s broom (Ruscus aculeatus) is a traditional herbal remedy that has also received some scientific attention for its effects on the capillaries and venous system. The root contains steroidal saponins, such as ruscogenin and neoruscogenin, which are believed to exert vasoconstrictive and anti-inflammatory effects. Historically, butcher’s broom has been used in Europe to support circulation, particularly for conditions like chronic venous insufficiency (CVI), hemorrhoids, and varicose veins, which involve capillary and vein health.

Scientific studies, including randomized controlled trials and meta-analyses, have investigated butcher’s broom extracts (often combined with hesperidin methyl chalcone and ascorbic acid) in the management of CVI. These studies suggest that butcher’s broom can reduce symptoms such as swelling, leg heaviness, and discomfort, likely by improving venous tone and capillary resistance. The most relevant mechanisms are attributed to the saponins, which may constrict venules and reduce capillary permeability.

However, while the evidence is positive, it is not overwhelming. Most clinical studies are small, and some combine butcher’s broom with other compounds, making it difficult to isolate its specific effects. Reviews and monographs, such as those by the European Medicines Agency (EMA) and German Commission E, recognize its traditional and scientific use for relieving discomfort of legs related to minor venous circulatory disturbances. Overall, the evidence is moderate, supporting a rating of 3 out of 5.
